I totally agree.
I've never seen a team where you could say having an average D would give you 4-5 more wins, minimum, so this is unchartered territory for us Sox fans.
Usually, it's almost always about pitching, then offense, but part of the reason our pitching looks so bad, is that they've needed to get 4 or 5 outs in way too many innings. Forget errors, It's all the non error blunders that cost us many runs and 5+ games.
BTW, we are 4.5 behind TEX.
Sure, better pitching or hitting could have made up those 5 games, but with the D, we are just making the point that average D wins us 5 more, Therein lies the rub for most fans.
